HARROW-CAR-T.

To all whom it may concern:

Be it known that I, JOHN B. BUNTEN, a citizen of the United States,residing at Mount Auburn, in the county of Benton and State of Iowa,have invented a new and useful Harrow-Cart of which the following is aspecification.

This invention relates to an improvement in harrow carts and consists inthe novel construction and arrangement of itsparts as hereinafter shownand described.

The object of the invention is to provide an attachmentfor a harrowwhich is adapted to support an operator who is so positioned upon theattachment as to balance or practically balance the parts upon thesupporting wheels.

l/Vith the above object in view the cart includes an axle supported bymeans of ground wheels and journaled in a frame. An operators seat isadjustably mounted upon the frame. Draft arms are pivotally connected attheir rear ends with the side portions of the frame and are pivotallyconnected at their forward ends with links which in turn are pivotallyconnected with the draft bar of a harrow.

In the accompanying drawings ;Figure 1 is a top plan view of the draftcart applied to a harrow. Fig. 2 is a transverse sectional view of theharrow cart cut on the line 22 of Fig. 1. Fig. 3 is a sectional view ofthe harrow cart cut on the line 33 of Fig. 1. Fig. 4 is a frontelevation of the draft bar of the harrow and attached parts.

The cart consists of an axle l which is supported at its ends uponground wheels 2. The axle 1 is journaled in a frame 8 which isapproximately U shaped and preferably formed from channel iron. A platet forms a portion of the frame 3 and is provided at its rear end with ahearing which receives the intermediate portion of the axle 1. A seat 5is adjustably mounted upon the plate 4.- and is so positioned that whenoccupied the weight of the occupant approximately balances the forwardportion of the harrow cart upon the axle 1 and the supporting wheels 2.A guide strip 6 is secured at its ends to the side portions of the frame8 and the intermediate portion of the said strip lies under theintermediate portion of the said frame and is spaced from the same. Arms7 are pivotally connected at their rear ends with the side portions ofthe frame 3. At their forward ends the arms 7 are pivotally c011-Specification of Letters Patent.

nected by means of pivoted links 7 with a draft bar 8 which in turn isconnected with a harrow section 9.

The links 7 are arranged in pairs, the inner ends of which are pivotallyconnected together and pivotally connected to the draft bar 8. Of eachpair of links 7 one member is located above the draft bar 8 and theother member is located below the same as illustrated in Fig. 4 of thedrawing. The outer end portions of the members of the pair of links 7are connected together by a pivot bolt which also serves as means forconnecting the forward ends of the arms 7 with the outer ends of thesaid links 7. The

last mentioned pivot bolt extends trans versely across the forward edgeof the draft bar 8 and when draft is applied to the said bar the saidpivot bolts are adapted to engage the forward edge of the bar and limitthe rearward swinging movement of the outer end portions of the links 7.

From the above description it will be seen that when draft is applied tothe bar 8 and the said bar together with the harrow section 9 is movedin a straight forward direction, the frame 3 and the axle 1andsupporting wheels 2 will trail behind the harrow section, but when aturn is made and the draft bar 8 is swung to one side or the other thearms 7 are moved longitudinally with relation to each other and the axle1 is turned so that the wheels 2 will continue to trail behind theharrow section 9 and the harrow section may be turned around in acomparatively small space. The intermediate portion of the frame 3 isconnected with the intermediate portion of the guide strip 6 by means ofbolts 10 which are located at the opposite sides of the plate 4 andlimit the swinging movement of the frame 3 and also prevent the arm 7from coming in contact with the bolts which secure the plate 1 to thesaid frame 3.

Having described the invention what I claim as new and desire to secureby Letters Patent is 1. In combination with a draft bar, a cartcomprising an axle, wheels supporting the same, a frame having hearingsin which the axle is journaled, a guide strip secured at each end to thesides of the frame and at its intermediate portion spaced from the lowerintermediate portion of the frame, and arms pivotally connected at theirforward ends with the draft bar and pivotally connected at their rearends with the side portions of the frame and lying in the space betweenthe guides and the frame.

2. In combination with a draft bar, a cart comprising an axle, wheelssupporting the same, an approximately U shaped frame having hearings inwhich the said axle is journaled, a plate connected at its forward endwith the frame and having at its rear portion a hearing which receivesthe axle, an operators seat adjustably mounted upon the plate a stripsecured at its ends to the sides of the frame and having itsintermediate portion spaced from the intermediate portion of the frame,arms pivotally con- 15 In testimony that I claim the foregoing as myown, I have hereto affixed my signature in the presence of twowitnesses.
